Just bought a new SSD I plan to swap into my MacBook pro (mid 2010 6.2). I plan on clean installing osx Lion and thought I would try to make the installation go as smoothly as possible by updatingthe  firmware, if needed, on both the new drive and the MacBook pro.


Model: MacBook Pro 6,2 (mid 2010) - 15" i5 2.4ghz

Current Boot ROM: MBP61.0057.B0C


I found updated firmware for my model MacBook pro:


"MacBook Pro (15-inch, Mid 2010)     MacBookPro6,2     MBP61.0057.B0F (EFI 2.6)"      


"System Requirements

OS X Lion 10.7.3 or later"



I'm wondering if I need to wait until os x Lion is installed before I install this update? Perhaps it will automatically via "software update" after Lion is installed. It looks like the fix is pertains to osx Lion functionality, so maybe it would've already been downloaded via software update if Lion was installed as opposed to snow leopard which is what I have currently.


The article says " If you are unsure whether your computer needs a particular update, simply download and open the update installer. The installer will alert you if the firmware update is already installed or not needed."

Which update installer are they referring to and where can I get it?


I thought it'd be better to update the firmware prior to installing the os, but maybe that's just an old habit I picked upnwhile using windows. Any advice would be greatly appreciated.

    Lion will ask you to install it when you finish the installation, so don't worry about that. You can also download the update and install it manually

    It's the file that you can download from that page instead of Software Update. It does the same. When you install it, don't power off your computer and connect it to the charger

    Depending one when your unit was actually produced (my 'late 2011,' for instance, was manufactured in February of 2012) the firmware updates may already be in place. They're usually included with "Software Updates" so I would check what firmware you have and whether you need the new patches or not.


    Good luck,
